We're just hours away from seeing the New England Patriots take on returning champions Seattle Seahawks in Super Bowl XLIX, as well as Katy Perry's highly-anticipated halftime show. Perry has been working closely with the NFL all month to promote the performance, which will air two quarters into tonight's game, starting at 6:30pm EST.

With all the given information from Perry and her promotional team, we've made up the playlist she's most likely to play:

1. RoarPerry has opened every Prismatic World Tour show with "Roar", so why not open her halftime show with the no. 1 single? Its upbeat feel and wildlife theme is sure to get the audience on its feet from the start.

2. Dark HorseSpeaking of getting the audience on its feet, they'll sure be standing when they do the "Dark Horse" dance.

3. E.T.After the spark provided by "Dark Horse", Perry will likely slow things down for a bit with "E.T." (with maybe a Kanye West appearance?).

4. Part of MeBefore being joined by Lenny Kravitz, Perry will have time for one more chart-topper—"Part of Me".

5. Are You Gonna Go My Way (with Lenny Kravitz)It's around this time when Lenny Kravitz will step onstage to perform with Perry.

6. American Woman (with Lenny Kravitz)Perry said that this year's halftime show will focus on female empowerment, so expect to see a little "American Woman" action with Kravitz.

7. Last Friday Night (T.G.I.F.) (with Missy Elliott)Perry announced earlier this week that Missy Elliott will be alongside her for the halftime show, so she'll likely join her for the remix of "Last Friday Night (T.G.I.F.)" the two pulled off in 2012 for the re-release of Perry's Teenage Dream.
